网易互娱4.18笔试
第二题小朋友猜拳，测试用例过，考虑到了起点可变等，但就是0%😭
求AC代码学习学习！附上我的代码（Java实现），求大佬指点！
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int t = Integer.parseInt(in.nextLine());
int[] ans = new int[t];
for (int i = 0; i < t; i++) {
String[] s = in.nextLine().trim().split("\\s");
int n = Integer.parseInt(s[0]);
int m = Integer.parseInt(s[1]);
char[] way = in.nextLine().trim().toCharArray();
ans[i] = findMaxRemain(n, m, way);
}
for (int i = 0; i < t; i++) {
System.out.println(ans[i]);
}
}
public static int findMaxRemain(int n, int m, char[] way) {
int maxRemain = 1;
//每个起点都试
for (int i = 0; i < n; i++) {
LinkedList<Character> child = new LinkedList<>();
for (int j = 0; j < way.length; j++) {
child.add(way[j]);
}
int index = i;
for (int j = 0; j < m; j++) {
index = index % child.size();
int next = (index + 1) % child.size();
int result = pk(child.get(index), child.get(next));
if (result > 0) {
child.remove(next);
} else if (result < 0) {
child.remove(index);
} else {
index++;
}
if (child.size() == 1) {
break;
}
}
maxRemain = Math.max(maxRemain, child.size());
}
return maxRemain;
}
//猜拳
public static int pk(char a, char b) {
if (a == b)
return 0;
else if ((a == 'R' && b == 'S') || (a == 'S' && b == 'C') || (a == 'C' && b == 'R'))
return 1;
else
return -1;
}
